BACKGROUND OF THE INVENTION

1. Field of the Invention

Aspects of the present invention relates to an information storagemedium, and more particularly, to a recording and/or reproducing method,and a recording and/or reproducing apparatus allowing recordingmanagement information to be easily retrieved from an informationstorage medium, and an information storage medium therefor.

2. Description of the Related Art

A Blue-ray disc recordable (BD-R) disc has a recording function whichcan replace a defect on the disc with a normal recording area. Thisfunction is referred to as a defect management function. Also, a userdata area of the disc can be divided into a plurality of sequentialrecording ranges (SRRs). In each SRR, incremental recording can beperformed and this incremental recording mode is referred to as asequential recording mode (SRM). Further, a write command of a host inrelation to an area in which data has been already recorded can insteadbe redirected to an area in which no data has been recorded. Thisfunction is referred to as a logical overwrite (LOW). These informationitems required for overall usage and management of the disc are storedin a place which is referred to as a temporary disc management area(TDMA). The TDMA is assigned and used in a lead-in area on the disc.Additionally, a part of a spare area in a user data area can beallocated and used as a TDMA. Accordingly, a plurality of TDMA areas canbe allocated on a disc.

TDMA information is divided into a temporary disc definition structure(TDDS), a temporary defect list (TDFL), and sequential recording rangeinformation (SRRI). Since a plurality of TDMA areas can be allocated, anaccess information area (ATDMA) is additionally required in order toeasily and quickly find location information on a location in which afinal TDMA is recorded.

The TDDS includes information on the size and location of an allocatedspare area, and location information on locations in which the SRRI andTDFL are recorded. The TDFL includes replacement information by LOW,information on a defect which is found while the disc is used, andreplacement information in relation to the defect. The SRRI includes SRRinformation in relation to sequential recording.

In the case of an information storage medium for recording, while theinformation storage medium is used for recording data, if a user onlydesires to use the information storage medium for reproduction withoutfurther recording data on the medium, then, the information storagemedium is finalized. When the information storage medium is finalized,final recording management information is copied from recordingmanagement information which was temporarily recorded, and is recordedinto a predetermined area. In this case, unless management of the finalrecording management information is performed well, it may becomedifficult to easily find the final recording management information inthe finalized information storage medium.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to the present embodiments of thepresent invention, examples of which are illustrated in the accompanyingdrawings, wherein like reference numerals refer to the like elementsthroughout. The embodiments are described below in order to explain thepresent invention by referring to the figures.

FIG. 1 is a diagram illustrating an example of a finalized informationstorage medium. Referring to FIG. 1, the finalized information storagemedium 100 includes a lead-in area 110, a data area 120, and a lead-outarea 130. In the data area 120, user data 121 is recorded. In thelead-in area 110 and the lead-out area 130, information on datarecording management or defect management, and disc managementinformation is recorded. While not required in all aspects, the medium100 can be a write once disc, such as a BD-R or a write-once HD-DVD, butis not limited thereto. Aspects of the invention can be applied torewriteable media as well as to non-optical media, such as magneticmedia.

While the information storage medium 100 is used by recording user datain the data area 120, if a user does not want to record data any moreand wants to use the information storage medium only for reproduction ofdata (that is, the information storage medium is desired to be used onlyfor reproduction without further recording data on the medium), then theuser performs finalization of the information storage medium 100.

There may be a variety of methods of finalizing an information storagemedium. A method will now be explained with reference to the exampleillustrated in FIG. 1. In order to prevent data from being recordedfurther on the data area 120, the remaining area in the data area 120where user data 121 has not been recorded is filled with predeterminedpadding data 122. Then, a final temporary disc management structure(TDMS) among TDMSs recorded in a temporary disc management area (TDMA)112 is copied into a disc management area (DMA) 111 and 131. Theremaining TDMSs relate to defects occurring during recording operationsprior to a last recording operation prior to finalization. Hereinafter,the TDMS copied into the DMA 111 and 131 will be referred to as a discmanagement structure (DMS). When data is reproduced from the thusfinalized information storage medium 100 in the future, the DMS is readfrom the DMA 111 and 131, and by referring to the read DMS, data isreproduced from the information storage medium 100. While not requiredin all aspects, the DMA and the TDMA can be referred to as or include aDefect Management Area and a Temporary Defect Management Area,respectively.

As described above, a TDMS includes a temporary disc definitionstructure (TDDS), a temporary defect list (TDFL), and sequentialrecording range information (SRRI). The TDMS is recorded in the TDMA112. Then, the TDDS, the TDFL, and the SRRI are updated in predeterminedunits as data is recorded to the information storage medium 100. Forexample, three types of units for updating the TDMS may be considered. Afirst TDMS update unit includes all of the TDFL, the SRRI, and the TDDS.A second TDMS update unit includes the SRRI and the TDDS. A third TDMSupdate unit includes the TDFL and the TDDS.

FIG. 2 is a diagram illustrating an example of the first TDMS updateunit. Referring to FIG. 2, the first TDMS update unit 200 includes aTDFL 210, padding data 220, SRRI 230, and a TDDS 240. The TDFL 210includes defect information, and the SRRI 230 includes recordingmanagement information. According to the amount of defects detected inan information storage medium or the information required for recordingmanagement, the sizes of the TDFL 210 and the SRRI 230 may be made to bevariable. In a method of flexibly setting the sizes of the TDFL 210 andthe SRRI 230, both having variable sizes, information in the TDFL 210 isrecorded from the farther end of the TDFL 210 from the SRRI 230 towardsthe SRRI 230, and information in the SRRI 230 is recorded from thefarther end of the SRRI 230 towards the TDFL 210 as illustrated in FIG.2. If the amount of data is insufficient, the padding data 220 is usedto fill the gap between the TDFL 210 and the SRRI 230. As such, thepadding data 220 need not be used in all aspects.

The remaining part in which data is not recorded between the TDFL 210and the SRRI 230 is filled with padding data 220. The TDDS 240 includesdisc definition information. In particular, because the sizes of theTDFL 210 and the SRRI 230 are variable, the TDDS 240 has a TDFL pointer242 and an SRRI pointer 241 which indicate the start addresses of theTDFL 210 and the SRRI 230, respectively. The TDDS 240 has a fixed size.In this way, the TDFL 210 and the SRRI 240 with variable sizes and theTDDS 240 with a fixed size are included in one update unit in an orderedarrangement of information structures, i.e., the TDFL 210, the SRRI 230,and the TDDS 240, in which the information structures are arranged inorder of the TDFL 210, the padding data 220, the SRRI 230, and the TDDS240.

FIG. 3A is a diagram illustrating an example in which the first TDMSupdate unit 200 illustrated in FIG. 2 is formed of one block. When thefirst TDMS update unit 200 can be recorded as one block, the first TDMSupdate unit 200 can have a shape as illustrated in FIG. 3A. When thefirst TDMS update unit 200 is recorded as more than one block, the firstTDMS update unit 200 can have a shape as illustrated in FIG. 3B by usingtwo blocks. In each case, the start locations of the TDFL 210 and theSRRI 230 are different, and therefore the TDDS 240 includes the SRRIpointer 241 and the TDFL pointer 242.

FIG. 4 is a diagram illustrating another example of a second TDMS updateunit 400. Referring to FIG. 4, the second TDMS update unit 400 includespadding data 410, SRRI 420, and a TDDS 430. The TDDS 430 is formed as afixed size of one sector, and includes an SRRI pointer 431 indicatingthe start address of the SRRI 420. The SRRI 420 is formed in a variablesize of K sectors. In the second TDMS update unit 400, the remainingpart which is not recorded as the SRRI 420 is filled with padding data410. In order to correspond to the structure of the first TDMS updateunit 200 illustrated in FIG. 2, the SRRI 420 is arranged adjacent to thelocation of the TDDS 430. If the amount of data is insufficient, thepadding data 410 is used to fill the gap. However, it is understood thatthe padding data 410 need not be used in all aspects.

Copying of a final TDMS having the shape of the second TDMS update unit400 illustrated in FIG. 4, into a DMA 111 or 131 when an informationstorage medium is finalized will now be explained. FIG. 5 is a referencediagram illustrating a concept of copying a final TDMS into a DMA 111 or131.

Referring to FIG. 5, a final TDMS 500 recorded in a TDMA 112 is formedwith padding data 510, final SRRI 520, and a final TDDS 530. Since thefinal TDDS 530 includes an SRRI pointer 531 indicating the start addressof the final SRRI 520, the start address of the final SRRI 520 can befound by using the final TDDS 530. When this information storage mediumis finalized, the final TDMS 500 in the TDMA 112 is copied into a DMA111. The final TDMS copied into the DMA 111 will be referred to as a DMS600. That is, the padding data 510, the final SRRI 520, and the finalTDDS 530 of the final TDMS 500 are copied as the padding data 610, theSRRI 620, and the DDS 630, respectively, of the DMS 600. If the amountof data is insufficient, the padding data 510 is used to fill the gap.However, it is understood that the padding data 510 need not be used inall aspects.

Referring to FIG. 6, the DMS 600 in the DMA 111 has the exact samecontents as those of the final TDMS 500. Accordingly, the SRRI pointer631 in the DDS 630 included in the DMS 600 indicates only the startaddress of the final SRRI 520 included in the final TDMS 500, but cannotindicate the start address of the SRRI 620 included in the DMS 600.Accordingly, the start address of the SRRI 620 of the DMS 600 cannot befound.

In order to solve this problem, according to an aspect of the presentinvention, when a final TDMS 500 recorded in a TDMA 112 is copied into aDMA 111 during finalization of an information storage medium 100, theTDMS 500 is not directly copied into the DMS 600. Instead, afterrearranging the information structures included in the TDMS 500, theTDMS is then copied into the DMS 600.

FIG. 7 is a reference diagram illustrating a concept of copying a finalTDMS 500 into a DMS 700 according to an embodiment of the presentinvention. Referring to FIG. 7, when a final TDMS 500 is copied into aDMS 700, a final TDDS 530 with a fixed size is copied as a DDS 710 inthe first location in the DMS 700. A final SRRI 520 with a variable sizeis arranged at a location following the DDS 710, and followed by paddingdata 730. That is, the SRRI 720 begins to be recorded in a data framefollowing a data frame in which the DDS 710 is finally recorded in theDMA 112 of the information storage medium 100, and meaningless data(i.e., the padding data 730) is recorded in the remaining data framesafter recording the DDS 710 and the SRRI 720. Thus, by arranging theSRRI 720 with a variable size following the DDS 710 with a fixed size,it can be known even without referring to an SRRI pointer included inthe DDS 710, that the SRRI 720 begins from a fixed location (i.e., aftera sector which is the fixed size of the DDS 710).

FIG. 8 is a diagram illustrating the contents of SRRI 720 illustrated inFIG. 7 according to an embodiment of the present invention. Referring toFIG. 8, the SRRI 720 includes SRRI header information 721 and SRR entryinformation 722. The SRR header information 721 includes an SRRI ID 723for identifying SRRI, and the number of SRR entries 724. The SRR entryinformation 722 includes SRR entry #1 725, SRR entry #2 726, through toSRR entry #N 727, an SRR terminator 728, and 00h 729.

FIG. 9 is a schematic diagram illustrating a structure of a recordingand/or reproducing apparatus 900 according to an embodiment of thepresent invention. Referring to FIG. 9, the recording and/or reproducingapparatus 900 can record data on or reproduce data from an informationstorage medium 10, and includes a recording/reading unit 920 and acontrol unit 910. According to control of the control unit 910, therecording/reading unit 920 records data on the disc 10 (that is, aninformation storage medium according to the present invention), andreads data from the disc 10 in order to reproduce the recorded data.

The control unit 910 controls the recording/reading unit 920 so thatdata can be recorded in predetermined recording unit blocks. The controlunit 910 also obtains valid data by processing data read by therecording/reading unit 920. In particular, according to aspects of thepresent invention, when a method of using the disc 10 changes, thecontrol unit 910 controls the recording/reading unit 920, therebyrearranging the order of a first information structure with a variablesize and a second information structure with a fixed size, both includedin management information of the disc 10, so that the first informationstructure with the variable size can be placed following the secondinformation structure with the fixed size, and then, the rearrangedmanagement information can be recorded to the disc 10. By way ofexample, the control unit 910 performs the rearranging described withreference to FIGS. 1 through 8 when the disc 10 is finalized.

FIG. 10 is a detailed diagram of the recording and/or reproducingapparatus 900 illustrated in FIG. 9 according to an embodiment of thepresent invention. Referring to FIG. 10, a disc drive has a pickup asthe recording/reading unit 920. A disc 10 is placed on the pickup. Also,as the control unit 910, the disc drive has a host interface (I/F) 911,a digital signal processor (DSP) 912, a radio frequency amplifier (RFAMP) 913, a servo 914, and a system controller 915.

While the disc 10 is used by recording data on the disc 10, if a userdoes not want to further record data on the disc 10, and wants to usethe disc 10 only for reproduction of data, the user commands a host 930to finalize the disc 10, and the host 930 transfers the finalizationcommand to the system controller 915 through the host I/F 911.

The system controller 915 receives the finalization command from thehost I/F 911 and performs finalization of the disc 10. In particular,according to an aspect of the present invention, when the informationstorage medium 10 is finalized, the order of SRRI 520 with a variablesize and a TDDS 530 with a fixed size, both of which are included in thefinal TDMS 500 of the disc 10, is rearranged so that the SRRI 720 withthe variable size can be placed following the TDDS 710 with the fixedsize. The final TDMS 700 may be stored in a memory of the systemcontroller 915 or may be recorded in a TDMA of the disc 10.

Then, the system controller 915 controls the DSP 912 and the servo 914so that the rearranged TDMS 700 can be recorded in a DMS 600 of a DMA112 of the disc 10. The DSP 212 adds additional data, such as a parityfor error correction, to the data that is to be recorded, and performserror correction code (ECC) encoding, thereby generating an ECC block,and modulates the ECC block according to predetermined methods. The RFAMP 913 converts the data output from the DSP 912 into an RF signal. Thepickup 920 records the RF signal output from the RF AMP 913 on the disc10. The servo 914 receives a command required for servo control, fromthe system controller 915, and performs servo control.

When data is reproduced, the host I/F 911 receives a reproductioncommand from the host 930. The system controller 915 performsinitialization required for the reproduction of the data.

The system controller 915 controls the recording/reading unit 920 sothat recording management data recorded in a predetermined area of thedisc 10 can be read. In particular, according to aspects of the presentinvention, when the disc 10 is finalized, the system controller 915controls the recording/reading unit 920 so that SRRI 720 can be readfrom a location following a DDS 710 in a DMA 112 of the disc 10. Then,recording management information included in the read SRRI is confirmed,and according to the recording management information, the data recordedon the disc 10 is reproduced.

The pickup emits a laser beam onto the disc 10, receives the reflectedlaser beam from the disc, and outputs an optical signal thus obtainedfrom the reflected laser beam. The RF AMP 913 converts the opticalsignal output from the pickup into an RF signal and provides modulateddata obtained from the RF signal, to the DSP 912. Also, the RF AMP 913provides a servo signal for control, obtained from the RF signal, to theservo 914. The DSP 912 demodulates the modulated data, performs ECCerror correction of the data, and outputs the thus obtained data.

Meanwhile, the servo 914 receives the servo signal from the RF AMP 913and the command required for servo control, from the system controller915, and performs servo control for the pickup. The host I/F 911transfers the data received from the DSP 912, to the host 930.

FIG. 11 is a flowchart illustrating operations of a method of recordingdata according to an embodiment of the present invention. While notrequired, aspects of the invention can implement all or part of themethod using computer software or firmware encoded on a computerreadable medium readable by a computer or processor, such as systemcontroller 915.

Referring to FIG. 11, the control unit 910 of the recording and/orreproducing apparatus 900 obtains a final TDMS 500 of a TDMA 111 when aninformation storage medium 100 is finalized in operation 11. The controlunit 910 rearranges the order of the SRRI 520 with a variable size and aTDDS 530 with a fixed size, both included in this final TDMS 500, sothat the SRRI 720 with the variable size is placed following the TDDS710 with the fixed size in operation 12.

The control unit 910 controls the recording/reading unit 920 so that therearranged final TDMS 700 can be recorded in a DMA 112. That is,according to the control by the control unit 910, the SRRI 720 isrecorded in a data frame following a data frame in which a DDS 710 isfinally recorded in the DMA 112, and meaningless data (i.e., paddingdata 730) is recorded in the remaining data frames after recording theDDS 710 and SRRI 720 in the DMA 112.

FIG. 12 is a flowchart illustrating operations of a method ofreproducing data according to an embodiment of the present invention.Referring to FIG. 12, the control unit 910 controls therecording/reading unit 920 so that SRRI 720 can be read from a locationfollowing a DDS 710 from a DMA 112 of a finalized information storagemedium 100. Where the medium is not finalized, the SRRI 230, 420 isdetected using the SRRI pointer 242, 431, of the TDDS 240, 430.

By referring to the read SRRI 720, the control unit 910 uses theinformation storage medium 100. That is, according to the contents ofthe SRRI 720, data is reproduced from the information storage medium100.

According to aspects of the present invention as described above,recording management information can be found in a fixed location of afinalized information storage medium, thereby allowing the recordingmanagement information to be found easily and quickly. However, it isunderstood that aspects of the invention can be applied during otheroperations beyond finalization of the medium, and that aspects can beused with data structures having multiple variable sizes and/or fixedsizes without being limited to the SRRI, TDFL, and TDDS structuresdescribed herein by way of non-limiting examples.

The present invention can also be embodied as computer readable codes ona computer readable recording medium. The computer readable recordingmedium is any data storage device that can store data which can bethereafter read by a computer system. Examples of the computer readablerecording medium include read-only memory (ROM), random-access memory(RAM), CD-ROMs, magnetic tapes, floppy disks, and optical data storagedevices. Further aspects can be embodied in carrier waves (such as datatransmission through the Internet). The computer readable recordingmedium can also be distributed over network coupled computer systems sothat the computer readable code is stored and executed in a distributedfashion. Also, functional programs, codes, and code segments foraccomplishing the present invention can be easily construed byprogrammers skilled in the art to which the present invention pertains.
